Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis Genet. Mol. Biol.
Santos,Carolina Gonçalves; Hartfelder,Klaus.
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees. In their co-evolution with angiosperm plants, the females of corbiculate bees have acquired a specialized structure on their hind legs for collecting pollen. In the highly eusocial bees (Apini and Meliponini), this structure is however only present in workers and absent in queens. By means of histological sections and cell proliferation analysis we followed the developmental dynamics of the hind legs of queens and workers in the fourth and fifth larval instars. In parallel, we generated subtractive cDNA libraries for hind leg discs of queen and worker larvae by means of a Representational...

Intra-puparial development of the Cochliomyia macellaria and Lucilia cuprina (Diptera, Calliphoridae) Rev. Bras. entomol.
Barros-Cordeiro,Karine Brenda; Pujol-Luz,José Roberto; Name,Khesller Patricia Olazia; Nair Báo,Sônia.
ABSTRACT The intra-puparial development of the blowflies Cochliomyia macellaria (n = 310) and Lucilia cuprina (n = 470), was studied under controlled conditions in laboratory. The 3rd instar larvae were reared until they stopped feeding, and the pre-pupae were separated according to the size in larval length and degree of pigmentation and of the cuticle. We observe a set of five continuous events or phases: (1) pupariation, (2) larva-pupa apolysis, (3) cryptocephalic pupa, (4) phanerocephalic pupa and (5) pharate adult. The total time of the intra-puparial development, larva-pupa apolysis to pharate adult, lasted for 120 h (5 days) to C. macellaria and 210 h (8.75 days) to L. cuprina.
